I am not quite satisfied as to the generic position of this species; it may possibly 
belong to Prionolema, Simon. 
Subfam. MEITN A. 
The spiders included in this subfamily comprise those usually known under the 
genera Argyroepeira, Meta, and Azilia. The name Argyroepeira becomes a synonym 
under Leucauge (cf. Ann. & Mag. Nat. Hist. (7) ix. p. 16]. The Metine differ from 
the Tetragnathine in having a rudimentary rounded boss at the base of the mandible 
on the outer side. ‘The vulva in the female is not simple as in Tetragnatha, but more 
or less developed externally. 
The web is of the usual orb type, and, like that of Tetragnatha, has an open space 
in the centre. The genera, several of which are treated as new, may be recognized by 
the characters given below :— 
GENERA. 
A. Femur iv. with a double row of tubercles in front, one-half to two- 
thirds from the base, bearing long, fine, curved ciliz. 
1. Tibie and protarsi i. and ii., in both sexes, studded with rows of 
triangular thorn-like cuspules soe eee - . . . . . PLESIOMETA, gen. nov. 
2. Tibiz and protarsi i. and i. not studded with cuspules. 
a. Posterior coxe closely situate, one-third of their diameter apart . Lxeucauer, White. 
b. Posterior coxze more widely separate, one full diameter apart . . Muecynomera, Simon.
